Automatic levelling
■
Place the appliance on a firm horizontal surface to work with auto-
matic levelling or fasten it onto a tripod via the 1/4" thread
■
After switching on, the automatic levelling system automatically
compensates for irregularities within the self-levelling range of
± 4° . Levelling is complete as soon as the laser lines no longer
move and the LED
■
If automatic levelling is not possible, e .g . because the underside
of the measuring tool is off the horizontal by more than 4° or be-
cause you are holding the appliance in your hand, then the LED
will light up red and the appliance will work without automatic
levelling . The laser lines will remain lit and flash, but the two
crossed lines will not necessarily run at right angles to each other .
When you are working without automatic levelling, this is always
indicated by the red LED
After vibrations or position changes during operation, the appliance
will always automatically re-level itself. To avoid errors, always check
the position of the horizontal and/or vertical laser line in relation to
reference points after re-levelling.
